CULTIVATOIR.

SPECIFICATION forming part 'of Letters Patent No. 297,035, dated April15, 1884.

Application filed November 28, 1883.

To all whom, it may concern:

Be it known that I, MARTIN A. TRAVIS, a citizen of the United States,residing at Hamburg, in the county of Fremont and State of Iowa, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention relates to cultivators which may be used for generalpurposes,- but which are more particularly adapted to the cultivation ofcorn; and it has for its object to provide a rigid frame for connectingtwo beams which shall be high enough to ride over the growing stalksjust before it is laid by without damaging the same.

In the annexed drawing, which is a perspective of my invention, andwhich makes a part olthis specification, A A represent two straightbeams.

B B represent shanks, which carry the ba les 0 (J, and which are rigidlysecured to the beams A.

D D represent the handles, connected to the beams.'

K K represent bars adjustabl'y connected to the beams near their frontends, which have their lower ends turned at right angles to the bars, toform shoes for supporting the forward ends of the beams.

E E represent standards made of metal, which have their lower endsrigidly secured to the beams at any suitable point between their ends.These standards are bent at right angles and inward near their centersand overlapping each other. The overlapping parts 6 e are provided witha series of holes, w,.through which bolts pass to secure the two partsfirmly together. By this arrangement the beams may be brought closertogether or separated, as the nature of the case may demand. At the cor-(No model.)

ners of thestandards frames at a are secured, which carry the pulleys aa. Over these pulleys is passed a chain or rope, F.

G Gare pulleys upon short shafts d d, which pass through the beams neartheir forward ends and at right angles to them. The chain F passes underthese pulleys, and each of its ends is secured to a whifiietree.

H H represent rods, which fasten at their forward ends to thewhiffletree through the eyes of the same links that the chains do. Therear ends of these rods pass back over the short shafts, and throughholes in platesi '5. These rods serve partly as guides and partly assupports for the whiffietrees. The chain passing freely over the pulleysallows the whil'iietrees toact as though they were a part of adoubletree.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, in a cultivator, of the standards E E, adjustablysecured together, and the beams A A and their attachments, the pulleys aa, the chain F, passing over the same, and the movable bars H H, passingthrough apertures in the plates i i, the bars having the ends of thechains attached to them, and the whifiietrees I, the bars by slidingback and forth serving to take up the slack of the chain as thestandards are adjusted, and the chain permitting the whiffietrecs to acttogether as a double-tree, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

MARTIN A. TRAVIS.
